First off: I'm a proper basshead and I really enjoy Chris'/HBBs views on most things audio-related. I wasn't expecting this to be an all-rounder of any sorts. But i'm thoroughly disappointed - even (and especially) as a basshead IEM. The bass is plenty, yes, but it feels bloated, not properly controlled and it lacks sub-bass to have proper impact, while there's simply too much upper low-end. The upper mids and the upper frequencies aren't just muffled, they're so weird that it's too much even for me (I'm very treble-sensitive and I need laid-back treble). The lack of controlled sub-bass and the weird top-end makes this the wrong IEM for the bass-heavy genres I enjoy (dubstep, riddim etc.). It works fine with something like doom metal/stoner rock and older hip-hop genres, I guess, but if I can't enjoy my go-to bass-heavy tracks with a dedicated basshead IEM, then there's something wrong with the set. This sounds like someone had too much fun with the EQ settings on a set that can't handle it.
